Bioelectromagnetics and Human Exposure
Bioelectromagnetics is the scientific study of how electromagnetic fields interact with biological systems, including the human body. As electronic devices become increasingly ubiquitous in modern life, understanding these interactions has become essential for engineers, safety professionals, and regulatory bodies. This field bridges physics, biology, and engineering to ensure that electromagnetic technologies can be safely deployed without adverse effects on human health.
The study of bioelectromagnetics encompasses a wide range of frequencies, from static and extremely low frequency (ELF) fields produced by power systems, through radiofrequency (RF) fields from wireless communications, to microwave and millimeter-wave radiation used in emerging technologies. Each frequency range presents unique interaction mechanisms and potential biological effects that must be understood, quantified, and properly managed through appropriate exposure standards and assessment methods.

About This Category
The Bioelectromagnetics and Human Exposure category addresses the critical intersection of electromagnetic technology and human safety. Engineers designing wireless devices, power systems, and medical equipment must understand how their products interact with the human body and comply with established safety standards. Healthcare providers and patients need to understand the implications of electromagnetic exposure, particularly regarding medical device interactions. This knowledge is fundamental to the responsible development and deployment of electromagnetic technologies in our increasingly connected world.
